Sule responding to queries on corruption charges levelled against NCP leaders, including party chief and her father Sharad Pawar, said many a times allegation are "baseless", and until and unless they are proved, the party cannot take action.
She was in the city to attend a one-day workshop on social media organised by the party.
"Social media networking is one of the strong online medium but it is often misused to bring bad name for people and party. Through the workshop, partymen must try to make positive use of it," Sule said.
On the forthcoming Assembly elections in Maharashtra, Sule said, "We are doing introspection and approaching people. We will avoid making mistakes done in the past (in general elections)."
Praising NCP's women wing, she said it is doing a laudable job to curb female foeticide and reduce malnutrition.
